Outcome ventricular septal defect Closure using the Nit-O

Abstract

Introduction: The main goal is to study outcome ventricular septal defect Closure using the Nit-Occlud Le VSD-Coil. Methodology: Following IRB approval from KAIMRC with number RC17/285/R, a retrospective chart review analysis were conducted of all pediatric patients with VSD who underwent transcatheter closure of VSD at King Abdul-Aziz Cardiac Center during the period from 2011till 2016. Demographic data, diagnosis, intraprocedure and post-procedure events were reviewed. Results: The patients referred for VSD interventional closure are 46 patients, 29 cases fulfill the criteria for VSD closure using Nit-Occlud Lê VSD-Coil, twenty-four patients of them had successful interventional closure of VSD with successful rate of 83% and 5 cases were referred to surgery due to device not fit or hemolysis. In this study, age group from 2 years up to 18 years. Ninety percent of VSD is the perimembranous (PM) type, 26 patients, and 3 patients (10%) with muscular VSD. From the 26 PM VSD cases 10 with TV accessory tissue partially covering the VSD defects. Immediate closure of the defect was achieved in 11/24 patients (45%); in five patients, there was tiny residual and 8 with small residual, at 6 months follow up only 6 patients with tiny residual VSD defect. Conclusion: The Nit-Occlud”-Lê VSD coil device with high safety level used for selected cases of VSDs. The device has minimal effects on the aortic and tricuspid valve, and there was no permanent AV block especially in patients with PM VSDs. Patients with a residual shunt should be followed, especially for the hemolysis.
